How long can boiled Chinese medicine be kept in the refrigerator?

My own experience. Because there is no preservative in the processing, even if it is vacuum packed, it can't be in the freezer for more than a week. If it needs to be kept for a long time, it should be kept in the freezer. But the longest period shall not exceed one month.

Suppose you have kept it in the refrigerator for more than a month. Look carefully to see if there are moldy white spots inside. If there is, it can't be used. If you haven't found it yet, open it and smell it for acidity or strange smell. If not, put it on the fire and heat it until it boils before continuing to take it. As long as it does not deteriorate, it will not affect the curative effect. There will be no side effects.

For reference only, I hope it will help you.
